LS rods in D-series motor
 

Are all B18 rods interchangable; such as 90-93 rods mismatched with 94-00 rods? I got a set of ls rods from a fellow H-T member for my z6 buildup but one rod was bent. Had another member send me a seperate rod, with different stampings on it. They look the same, just different stampings (PR4 86 & PR4 54).

*edit* I'm a noob at engine overhauls so bare with me guys. What does brushing the rods do, becuase I searched and some people said to brush the small end of the rod... Can someone clarify this for me. And if anybody reading this post is familiar with this swap, please give me some pointers as on the steps needed to make this work with my stock z6 pistons. Thanks,
Nick

All LS rods should be the same but I would have them balanced if they are from different engines

Re: LS rods in D-series motor (yellaboi)
 

i did this before.... ls rods in a d block. call crower and tell them you need a rebushing kit for the ls rods. theyll know just explain to them what you are doing. i think i ran me like 38 or 48 bucks for the kit. balance them and shotpeened them while you are at it.

What exactly is this rebrushing kit? do i have to send my rods, crank, and pistons to them? Or is this a DIYS kit?

Re: LS rods in D-series motor (AlphaQup)
 

nope just tell them thats what you need. and then purchase it from crower and when you recieve it take it to the machin shop to have them install it.

Re: LS rods in D-series motor (DXturbo)
 

so you can use ls rods in a d16a6. if i got some what needs done to the rod to get it to work with d pistons and the d crank? i can take it to a machine shop, i guess i could just tell them to make sure the rods work with the other parts and they can figure it out. but just so i know whats going on please inform me.. thanks

I think his SN is turbopanda https://honda-tech.com/forums/images/smilies/emwink.gif try a search

Re: LS rods in D-series motor (DSeriesBKilla)
 

he aint joking dude.

you can use the supra rods which are sort of tall, and the shorter than D b16 pistons....at least from my understanding is hwo it works. comes out to the same hieight as stock d16 rods/pistons....but obviously MUCH stronger.

Re: LS rods in D-series motor (AlphaQup)
 

do you have to modify the ls rod to fit in there at all? like shave it or nething?

is this setup cheaper than buying eagle rods and srp pistons?? or is it a bitch to find 4 rods and the b16 pistons

Re: (1dumbassscreenname)
 

that combo was b16a rods with 1g-gte old gen supra pistons that are forged because that was turbo from the factory. Moddification is needed to get it all to work together. its like $520.

so do LS rods really work and if so what needs done??

ls rods work as mentioned above all u need is the bushing kit.

Re: (sohc_boy)
 

LS rods work, from my understanding you need to notch the block to get them to fit.....never heard of the brushing kit...

it was supra pistons 75mm and b16a rods.....dropped the compression to like 8:1 for higher boost apps!!

my understanding is that the rods are also 2mm too wide at the crank end and have to be shaved. There was a big discussion on how to do this on http://www.dseries.org a while back. General concensus was that you could use LS rods, but by the time you bought the rods, bushings, and had the machine work done, you had spent nearly $300 for used/re-worked rods, while a new set of Eagle rods is about $330.

I'd send them back and demand an LS6

you might as well just get Eagle Rods instead of LS rods...

they are stronger and just about the same price, and the Eagle rods won't take as long to istall, as there is no machiene work to be done.

Re: (GSRswapandbanned)
 

so b18 eagle rods work in the d16, with out problems? does it change the compression ratio? i want to nkow because im ready to buy the stuff i just need to find the right price and parts.

Re: (toyosupr)
 

If you have to mod the STOCK b rods to make them work what do you think the likely hood of BIGGER (in just about every aspect besides stroke) working would be...

Short answer NO... they will not drop right in... but if you're buying eagle rods then WHY would you buy them for a different app... the d rods they make will handle similar power... the rods will NOT be your weak point if you get d rods instead of b (from eagle etc.).
